Comic-Con returns to the San Diego Convention Center this summer, from July 20 through July 23; preview night is on July 19.

Comic-Con was born in 1970 in the basement of the U.S. Grant Hotel in the heart of San Diego, California. Over the decades, the “little event that could” has grown into a behemoth, taking over the Convention Center, neighboring hotels and downtown San Diego for a long summer weekend every year.

Comic-Con’s fervent fans typically attend the convention in elaborate costumes, transforming the city into a metropolis straight out of the pages of fantasy and science fiction. The event has also become famous for celebrity sightings.
